The Replacement Letters

Dear Celestia The Goon

That childish friend of mine Pinkie Pie needs to learn that there's 'breaking a promise' and settling a friendship problem.

Photo finish asked Rarity for a new look, so Rarity asked Fluttershy to be her model, and that jerk Photo Finish dared to make poor Fluttershy a model. A model whose fans don't know her own history (they were mean to poor Rarity).

Fluttershy didn't want to be a model (which should have been painfully obvious to Rarity) but didn't want Rarity to know because she thought Rarity wanted her to be a model; as for Rarity, she was jealous of FLuttershy and thought Fluttershy wanted to be a model. I tried to be a good friend to them, but I made a pinkie promise to not tell the other of her feelings. I tried to tell them but that nutcase Pinkie didn't want me to break a pinkie promise.

I learned that pinkie promises are nothing but trouble.
